Supporting empty Location URIs.

An empty string in Location was being handled specially by not sending a
Location header. This may occur after variable resolution, so we need to
consider this scenario.

The obsolete RFC 2616 defined the Location header as consisting of an absolute
URI <https://www.rfc-editor.org/rfc/rfc2616#section-14.30>, which cannot be an
empty string. However, the current RFC 7231 allows the Location to be a
relative URI <https://www.rfc-editor.org/rfc/rfc7231#section-7.1.2>, and a
relative URI may be an empty string <https://stackoverflow.com/a/43338457>.

Due to these considerations, this patch allows sending an empty Location header
without handling this case specially. This behavior will probably be more
straightforward to users, too. It also simplifies the code, which is now more
readable, fast, and conformant to the current RFC. We're skipping an
allocation at request time in a common case such as "action": {"return": 404}

Supporting variables in "location".

............
Description:
............

Before this commit, the encoded URI could be calculated at
configuration time. Now, since variables can only be resolved at
request time, we have different situations:

- "location" contains no variables:

In this case, we still encode the URI in the conf structure, at
configuration time, and then we just copy the resulting string
to the ctx structure at request time.

- "location" contains variables:

In this case, we compile the var string at configure time, then
when we resolve it at request time, and then we encode the
string.

In both cases, as was being done before, if the string is empty,
either before or after resolving variables, we skip the encoding.

...........
Usefulness:
...........

An example of why this feature may be useful is redirecting HTTP
to HTTPS with something like:

"action": {
"return": 301,
"location": "https://${host}${uri}"
}

.....
Bugs:
.....

This feature conflicts with the relevant RFCs in the following:

'$' is used for Unit variables, but '$' is a reserved character in
a URI, to be used as a sub-delimiter. However, it's almost never
used as that, and in fact, other parts of Unit already conflict
with '$' being a reserved character for use as a sub-delimiter, so
this is at least consistent in that sense. VBart suggested an
easy workaround if we ever need it: adding a variable '$sign'
which resolves to a literal '$'.

......
Notes:
......

An empty string is handled as if "location" wasn't specified at
all, so no Location header is sent.

This is incorrect, and the code is slightly misleading.

The Location header consists of a URI-reference[1], which might be
a relative one, which itself might consist of an empty string[2].

[1]: <https://www.rfc-editor.org/rfc/rfc7231#section-7.1.2>
[2]: <https://stackoverflow.com/a/43338457>

Now that we have variables, it's more likely that an empty
Location header will be requested, and we should handle it
correctly.

I think in a future commit we should modify the code to allow
differentiating between an unset "location" and an empty one,
which should be treated as any other "location" string.

Python: fixing incorrect function object dereference.

The __call__ method can be native and not be a PyFunction type. A type check
is thus required before accessing op_code and other fields.

Reproduced on Ubuntu 21.04, Python 3.9.4 and Falcon framework: here, the
App.__call__ method is compiled with Cython, so accessing op_code->co_flags is
invalid; accidentally, the COROUTINE bit is set which forces the Python module
into the ASGI mode.

The workaround is explicit protocol specification.

Note: it is impossible to specify the legacy mode for ASGI.

In PHP, custom fastcgi_finish_request() and overloaded chdir() functions can be
invoked by an OPcache preloading script (it runs when php_module_startup() is
called in the app process setup handler). In this case, there was no runtime
context set so trying to access it caused a segmentation fault.
